BEVERAGE-DISIEI1TSI1TG APPARATUS.

Application filed August 6, 1926. Serial No. 127,619.

My invention has relation to im ments in faucets of the duplex type, t

roveat 1s,

those having capacity to discharge twodifpose butone water port and one syrup port.

The present invention embodies a water port and a syrup port and in addition thereto, an auxiliary'water port for admitting a fine stream of carbonated water which on commingling with the syrup, produces a foamy or frothy drink preferredby some people. On the other hand,. if it is desired, a. coarse stream of'water may be admltted to the faucet nozzle. with the syrup for producing a flat drink, that is, one having but little foam. These results are obtained. by a proper manipulation of the faucet handle as will be more fully apparent, together with the other advantages of the invention, from a detailed description thereof in connection with the accompanying drawings, in which Fig. 1 represents a plan view of my improved faucet with parts of the connections thereto'broken away; Fig. 2 is a vertical longitudinal section taken on the line 22 "of Fig. 1; Fig. 3 is avertical, longitudinal section taken on the line 3-3 of Fig. 1; Fig. 4 is a horizontal, transverse section taken on the line 4-4 of Fig. 2; and Fig. 5 is a bottom plan of a faucet handle showing the cam formations for actuating the water and syrup valves. I

Referring to the drawings, 1 represents a casing in which are symmetrically disposed awater valve chamber 2 and a syrup valve chamber 3, the upper part a of sa1d chamber 2 being of a smaller bore than the lower part b, there being thus formed a shoulder a at about the middle of the chamber 2. The syrup valve chamber 3 is similarly formed, having its upper part a smaller than its lower part b, and a shoulder 0. at the juncture of the bores a and b. A pipe 4is screw-threaded into the casing 1 so as to communicate with the enlarged part b of valve chamber 2 and 'a pipe 5 is screwthreaded into said casing so as to communicate withthe enlarged part b of syrup valve chamber 3, the pipe 4 leading to the carbonated water supply and the pipe 5 leading to the syrup supply.

The casing 1' 1s provided with a water Jort 6 on the same side with the valve chamer 2, said port 6 communicatingwiththe part a of chamber 2 by means, of a plurality of transverse passageways 7. Alongside the port 6 is an auxiliary port 8 of small diameter, said port 8 also communicating with the chamber a by means of atransversej -pas-. sageway 9 disposed ina plane below the passageway7, and a nozzle 10 is-screwed. into the lower end of the auxiliary port 8, said nozzle having a small aperture 11 in its lower extremity. The casing'l is also provided with a syrup port 12 adjacent to the -valve chamber 3, said syrup port extending entirely through the casing and being closed at the upper end by a syrup gage screw 13 which is adapted to be screwed inwardly or outwardly to control the amount of passage- Way 14 that communicateswith port 12. said passageway 14 also communicating with the port a of valve chamber 3.

A valve 15 is disposed in the chamber 2, said valve comprising a cylindrical part d from which extends downwardly a reduced portion 6 and upwardly a reduced portion f. A valve tip 16 is disposed in the part a of chamber 2, said tip bearing against a gasket 17 disposed between the up and the upper end of valve portion 7, the rounded nose of the valve tip 16 projecting upward beyond the top surface 18 of easing 1. A spring 19 1s coiled about the stem e and is held in the part b of chamber 2 by a screw plug 20,

said spring exerting its tension to maintain the cylindrical partd of the valve (which is the valve proper) against the shoulder 0,

thus shutting- 01f communication between the parts 6 and a of the chamber 2. This is the closed position of the valve and in this position it will be noted the passageway 7 leading to port 6 is slightly below the gasket.

17, the passageway 9 leading to port 8 being below the passageway 7 so 'thata partial movement of the valve 15 downwardly is possible to unseat the valve proper (1 without closing the passageway 7 and a further movement of the valve downward-1y will shut off the passageway 7 from communication with the part a of chamber 2.

cWithin the valve chamber 3 is a valve 21 shaped similarly to valve 15 and a spring 22 is held in the part b of chamber 3 by a plug 23, said spring operating to maintain the valve on the shoulder 0' unless its tension is overcome. Valve 21 is also provided with a valve tip 24, the rounded nose of which extends above the top surface 18 of easing 1 and by referring to Fig. 3, it will be seen that the gasket 25 is capable of its maximum downward movement without closing olfcthe passageway 14 leading from the part a'flof chamber 3 to syrup port 12. Thus, for any amount of downward movement of the valve 21, the valve will be unseated and allow free communication between the part b of chamber 3 and port 12.

By referring to Fig. 4, it will be seen that the port 8 is in close proximity to the syrup port 12 and if the nozzle 10 is turned to the proper position, the aperture 11 will point directly at the port 12 so that when carbonated water is discharged from said aperture, it will be projected i uto the stream issuing from port 12, thus churning up the syrup which together with the velocity of the stream of carbonated water issuing from said aperture, produces a frothy drink.

A stud 26 projects upwardly from the center of the top surface 18 of easing 1 and has a handle 27 mounted for rotation upon it, the stud passing through an opening 28 in the cam disc 29 of the handle, a nut being screwed over the extremity of the stud 26 to hold the handle in place. On the inside of the disc 29 there are oppositely disposed depressions 30, 31 to receive the valve caps 16 and 24: when the handle 27 is in its normal position, that is, the position in which the faucet valves are closed. An inclined arcuate cam surface 32 extends from the depression 30 around toward the center line a: of the handle where said cam surface merges with the innermost surface 33 of the cam disc 29. Extending from the depression 30 in the opposite direction to the cam surface 32, is a cam surface 34 merging with plane surface 35 some distance inwardly from the surface 33 so that the rise of the cam surface 34 is considerably less than the rise of cam surface 32. An inclined arcuate cam surface 36 extends from depression 31 in a direction toward the cam surface 32 and merges with the plane surface 33 while a cam surface 37 extends from the depression 31 in a direction opposite to cam surface 36, the cam surface 37 mergin with a plane surface 38 in the same p ane with surface 33. Consequently, when the handle 27 is rotated to cause valve tip 16 to ride upon inclined surface 32, the valve will depressed to its greatest extent and will close passageway 7, but if the handle 27 is rotated m the opposite direction, the valve tip 16 will ride upon the cam surface 34 and the valve will be slightly depressed so as not to cover the passageway 7 Since the depths of cam surface 36 and 37 are the same, the valve 21 will be depressed the same amount for either direction of rotation of the handle 27. In order to arrest the movement of the handle 27, confining said movement between the limits nccessai to effect the operation of valves as descnbed, a stop pin 39 projects upwardly from the casing 1, said pin being located on the center line a: of the handle when the handle is in its normal position, but riding in the arcuate depression 40 to encounter either end wall 4.1 or 42 of the depression 40 depending upon which direction the handle is rotated.

It will be seen that with a movement of the handle 27 in one direction, the valve 15 will be partially depressed and the valve 21 will be fully depressed causing a stream of syrup and carbonated water to pour from the nozzle N of the faucet; while if the handle is rotated in the opposite direction, the valves 15 and 21 will both be fully depressed causing a flow of syrupwand a fine stream of carbonated water to projected through the syrup stream and a foamy mixture discharged from the nozzle N.
